In this condition it Will'be seen ythat the claw or projection js lhas raised the detent or Apawl 171, away from the ratchet teeth g3, thereby rendering same ineffectivey and enabling the ltelescopic'parts to be slid iutoany desired position of adjustmentat'rvill. WVhen the desired position ofadjustmen't has been-obtained, the hinged member 'i is movedinto alignmentvvith the'telescopio parts g-and h,

the claw vor projection jg' assuming the i@osition shown in the Figure 3, and permitting the detent orpawl h to'engage the ratchet teeth g3, thus positively preventing any eX- tension of the hinge. f y

The ,telescopic lparts gy and h can, however, intliis condition be elosedlor collapsed, this being desirable Where a case of variable ca pacity after being fastened is so filled that it may be reduced by a-simple pressure applied to the upper part of the case.

It has been found, however, 'that this collapsing of the case after it has been filled is sometimes deficient inasmuch as a comfortably filled case may have very heavy luggage placed thereon and on further collapse ofthe case consequent damage to the articles obtained therein. To avoid this, an independently operable member may be associated with the telescopic mechanism in themanner illustrated in Figure 7. 7c is the member pivotally mounted upon extensions of the pin jz and provided Witha peg or pin lo adapted to be engaged with any one of a plurality of apertures gin the outerpart g by manipulation. That is to say, When the mechanism has been'brought to the position shown in Figure 3, the member la may be pressed by the linger so that its pin 7c engages any one of the apertures g5, and thereby positively fastens the telescopic elements so that no collapse or extension thereof can positively take place. When the hinged member j is l released and rocked on its pivot, by the spring jt, the link 7' disengages the member 7c and renders same inoperative. The member c maybe normally held in the position illustrated relative to the link CZ as for instance by friction.

It Will be appreciated that instead of employing ratchet'mechanism in the present invention, such as that illustrated, a tooth ber pivoted to the sliding inner part thereof,

and a link device connecting the said sliding inner part With the hinged member externally of the telescopic member, and adapted to be ldisplaced into adjacency with the said telescopic member to secure the parts thereof against extension.

2. An extensible hinge for a receptacle of variable capacity, comprising in combination a two-part telescopic member, a hinged member pivoted to the sliding inner part thereof,

Y a link device pivotally connected to said sliding inner member at its one extremity and to the hinged member at its opposite extremity externally of the telescopic member, and adapted togbe displaced into adjacency with the telescopic member to secure the parts ythereof against extension.

3. vAn extensible hinge for a receptacle of variable capacity, comprising in combination a two-part telescopic member, a hinged member pivoted to the sliding inner part thereof, a link device pivotally connected to said Vsliding inner member at its one extremy bination a two-part telescopic member, a

hinged member pivoted to the sliding inner part thereof, alink pivoted to said hinged member and adapted to slide relative to said sliding inner part, saidlink being provided externally of the said telescopic member. and

fA'n extensible hinge for a`receptacleof variable capacity, comprising in combination a two-part telescopic member, a hinged member pivoted tothe sliding inner part thereof, an internal catch mechanism disposed Within the telescopic member adapted to secure the sliding inner part in relation to the stationary outer part, and means controlling Lsaid catch mechanism comprising a link exterl nally connecting the sliding inner part with said hinged member.
